Be careful. Any pursuit that diminishes people’s reliance on the Bible is fraught with grave spiritual dangers—especially if it is something that leads gullible souls into superstition, gnosticism, occultism, New Age philosophies, or any kind of spiritual confusion. Those are undeniably the roads most traveled by people who feed a morbid craving for detailed information about the afterlife, devouring stories of people who claim to have gone to the realm of the dead and returned.
It is sinfully wrong to try to investigate spiritual mysteries using occult means. And it is seriously dangerous to listen to anyone who claims to know more about God, heaven, angels, or the afterlife than God Himself has revealed to us in Scripture. Quotes from the link.
